The answer is B.

When trying to solve this you first look at how many numbers should it be. If it starts at 4 million then you know its 7 numbers, so any that are longer than that can be dropped. Compare the remaining options and see what is different then read out the whole question.

A simple random sample of 50 items from a population with 7 resulted in a sample mean of 35.
Vilka [71]

The 90% , 99% confidence interval for the population mean is 32.145 < \rm \mu < 35.855 and 31.093 <  \rm \mu < 36.907

<h3>What is Probability ?</h3>

Probability is the study of likeliness of an event to happen.

It is given that

Total Population = 50

Mean = 35

The confidence interval is given by

\rm CI = \mu + z \dfrac{s}{\sqrt n}

\rm \mu is the mean

z is the confidence level value

s is the standard deviation

n is the population width

(a) The 90% confidence interval for the population mean

90% \rm \alpha / 2  = 0.05

Z = 1.64

34 \rm \pm 1.64 * 8 / √50

34 \rm \pm  1.855

32.145 < \rm \mu < 35.855

(b)  The 99% confidence interval for the population mean

99% \rm \alpha / 2  = 0.005

Z=2.57

34  \rm \pm 2.57 * 8 / √50

34 \rm \pm  2.907

31.093 <  \rm \mu < 36.907

Therefore the confidence interval for population mean has been determined.

The complete question is

A simple random sample of 50 items from a population width =7  resulted in a sample mean of 35. If required, round your answers to two decimal places.

a. Provide a 90% confidence interval for the population mean

b. Provide a 99% confidence interval for the population mean

Answer:

If x is the size of the child's head, 5 times that would be 5x and "plus 4/5" is + 4/5 so the equation is y = 5x + 4/5.

Given f(x) = 4(x - 8), determine the value of f(10).
Ilya [14]

Answer:

f(10) = 8

Step-by-step explanation:

f(x) = 4(x - 8)

Let x = 10

f(10) = 4 ( 10-8)

       = 4 ( 2)

      = 8
